Product details
Overview
R7F100GPL3CFB#AA0 from Renesas is a 100-pin LFQFP, 5.0-V tolerant, industrial-grade RL78/G23 16-bit MCU with 512 KB code flash, 48 KB RAM, and integrated capacitive touch sensing (CTSU2L), designed for low-power HMI and sensor-fused control in factory automation and smart building systems.
For engineers reviewing the R7F100GPL3CFB#AA0 datasheet, R7F100GPL3CFB#AA0 pinout, R7F100GPL3CFB#AA0 application, or R7F100GPL3CFB#AA0 equivalent, this page delivers verified package mapping, confirmed SNOOZE mode sequencer operation, real-time clock accuracy, UARTA/LIN support, and validated alternative selection guidance for production design-in.
Technical Context
The R7F100GPL3CFB#AA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), and integrates a SNOOZE mode sequencer (SMS) that executes up to 32 preconfigured commands-including ADC sampling, comparator comparison, and CTSU2L scanning-without CPU wake-up.
It features dual-clock domain operation: high-speed on-chip oscillator (±1.0% accuracy at 1.8–5.5 V, −20 to +85°C) and subsystem clock (32.768 kHz ±20% with adjustability), enabling precise RTC operation and ultra-low-power data retention at 210 nA for 4 KB RAM.

Can the R7F100GPL3CFB#AA0 perform background data flash writes while executing code from program memory?
Yes, the R7F100GPL3CFB#AA0 supports Background Operation (BGO) for its 8 KB data flash memory, allowing full CPU execution from code flash during erase/write cycles. This is confirmed in Section 1.1 of the RL78/G23 datasheet Rev.1.40 and enables concurrent firmware updates and real-time control without interruption.
Which pins on the R7F100GPL3CFB#AA0 are designated for the capacitive touch sensing unit (CTSU2L), and what configurations do they support?
The R7F100GPL3CFB#AA0 uses P30 (TSCAP) as the reference capacitor terminal and supports up to 26 additional pins (e.g., P147, P120, P20–P25, P00–P01, P31, P50–P51, P60–P62, P70–P73) as CTSU2L input channels.
